Version number now set in configure, available through Makefile.global
and config.h. Adjusted all referring code. Scrapped pg_version and changed initdb accordingly. Integrated src/utils/version.c into src/backend/utils/init/miscinit.c. Changed all callers. Set version number to `7.1devel'. (Non-numeric version suffixes now allowed.)
